Abstract

The present invention is of system, device, and method for detecting and localizing obstruction in a blood vessel (110). More particularly, the present invention is of a balloon catheter (201) having an expandable balloon (200) which comprises a plurality of strain gauges (202a,b,c;212a,b,c;222a,b,c) operable to report relative degrees of expansion of local portions of a wall of the expandable balloon (200). Incomplete expansion of a local portion of the balloon (200), under common pressure within the balloon (200), indicates presence of an obstruction, such as a region of plaque, within the blood vessel (110).
